Visser | October 22, 1996 |
A point-of-use water filtration and dispensing unit including an unfiltered water storage container removably supported above a filtered water reservoir. The container has an inlet for unfiltered water and an outlet communicating with the reservoir, with the water in the container being exposed to atmospheric pressure. The filtered water reservoir communicates with a dispensing outlet having tap means which in its closed position resists the hydrostatic pressure of the water in the reservoir and the container. A seal removably seals the reservoir to the container, and a filter is removably located within the unfiltered water container such that water flows through said filter by gravity feed as filtered water is dispensed from the reservoir.
